Brassiere

ABSTRACT

A brassiere includes a left cup, a right cup, and a bra body, wherein a cup size of the left cup cavity is different from a cup size of the right cup cavity. The bra body is for selectively retaining the left cup and the right cup in position to form a brassiere structure, in such a manner that a wearer with asymmetrical breasts is able to individually select the left and right cups according to the left and right breast sizes respectively to optimize the support of the breasts of the wearer for supporting the weight of the breasts and positioning the left and right cups covering left and right breasts of wearer respectively.

BACKGROUND OF THE PRESENT INVENTION

1. Field of Invention

The present invention relates to an underwear garment, and more particularly to a brassiere (bra) which is able to independently select the left cup size and right cup size for correctly fitting the asymmetrical breasts of wearer.

2. Description of Related Arts

The brassiere (bra) is a common female garment for covering, supporting, or shaping the breasts of female. Normally, the brassiere has two cone shaped cups for enclosing and supporting the breasts and a chest band for spacedly interconnecting the two cups for surrounding at the underbust, so as to mainly support the breast weight via the chest band through the cone shaped cups. The chest band normally has a set of sliding fastener for slidably adjusting and fastening the chest band at the back side of the wearer in accordance with the size of the underbust thereof, so that the chest band is able to fittedly sit at the underbust of wearer. The bra may further have one or more shoulder straps for assistantly supporting breasts. Although the shoulder straps are optional, the correctly fitted brassiere is still able to support the breast solely by the chest band thereof.

In order to give best support of the breast and avoid bumps and seams in the cups, the brassieres have to be correctly sized to fit the breasts of each of the wearers. The bra may be also designed for perfectly fitting on the breasts of wearer, so that the bra is able to shape the breasts as the desire of the wear, such as enhancing the cleavage or lifting up the breasts of wearer. The poor fitness of the brassiere can dramatically reduce the function of the bra and decrease the performance that the brassiere was originally designed for. More seriously, the incorrect size of bra may cause serious pain, discomfort, or even deforming the original shape of the breasts to an unwanted shape. One example is that the poor fitted bra may shift the supporting force of bra from the chest band to the shoulder straps, so that the weight of the breasts will mainly load on the shoulder or the neck to cause the neck joint injury. The breast weight carried by the shoulder rather than the chest band may also result in the contribution of back pain and/or shoulder pain.

Currently, each brand of the bra manufactures roughly has the combinations of back size and the cup size, so that the wears are able to select a better fitted bra for supporting their breasts in accordance with the aspects of individual sizes of underbust and the height of breasts. For instances, the size of 32A bra has a peripheral length of the underbust of 32 inches and cup size of A, which is the scale of bra depending on the height from the bottom of the cone shaped cup to the apex of the cone shaped cup; or the size of 36G bra has a peripheral length of the underbust of 36 inches and cup size of G. Therefore, the wearer is able to select a pair of symmetric cups of the bra according to her own size of underbust and the breasts.

However, a significant number of women are having troubles of finding a correct size bra. The rough standard of the current brassiere is unable to accurately fit the individual sizes and contours of wears' breasts. One of the most common problems is that most women's breasts are asymmetrical. According to the researches, 62% of women have the left breast larger than the right breast, especially for women having larger size breasts. In this case, the existing brassies are only possible to fit one of the breasts of the wearer.

For instances, the wearer with asymmetrical breasts may have to select the bra which fits the larger left breast, so that the smaller right breast has a loosen fit in relation to the left cup of the bra; and conversely, the wearer with asymmetrical breasts may have to choose the bra which fits the smaller left breast of the wearer, so that the larger right breast may have to be squished and deformed for being enclosed by the right cups of bra. Therefore, the bra wearer, especially for the female wearer having the asymmetrical breasts, has a difficult time finding a correctly fit of bra for best supporting and covering her breasts. The poor fit of bra due to the asymmetrical breast of women may also cause the above mentioned problems, such as pains and the deformation of original shape of breasts. The wearer is unable to buy a bra for individually fitting each of the left and right breasts thereof.

The padding may be provided for inserting into a rear compartment of the cup in order to slightly adjust the volume and receiving cavity of the cup, so that the bra may be able to provide a little bit better fit for asymmetrical breasts of wearer. However, the padding within the rear compartment of the cup tends to have the unwanted lateral movements therein, so that the cup with the padding will be easily deformed to cause the un-comfortableness and/or the pains due to incorrectly transfer the supporting force of the bra to the undesired location. In addition, the inserted padding elements are unable to adjust the size of the receiving cavity of the cup with a relatively larger difference. For instance, when the breasts are one cup size different, such as size B of left breast and size C for right breast, the padding is hardly to fill the difference of the receiving cavity of bra.

The wearer may be able to purchase a perfect fit bra by ordering a customized bra, which could take the sizes of individually asymmetrical left and right breasts into account, so that the two cups of the bra integrally connected with each other by the chest band are able to perfectly fit the breasts. However, the custom-made brassiere is expensive and non-affordable for most of the wearer. The wearer also has to inconveniently go to the specific bra customizing shop for measuring and tailoring the size and shape of the breasts thereof. It is time consuming that the wearer may have to pick it up after the customized brassiere is made.

Therefore, the shoulder straps 30 are able to across the top shoulder of the wear to assistantly support the weight of breasts thereof.

As will be readily appreciated that the detachably shoulder straps 30 are able to transform the bra into variety of styles thereof, so that the wearer is able to selectively and detachably form the desired style of the shoulder straps 30 according to the formations of the outer garment that the wearer is going to wear. Other applications or formations of detachably shoulder straps 30 are shown in FIGS. 3 and 4 of the drawings. In the FIG. 3, only one shoulder strap 30 is detachably connecting to the left and right cups 10, 10′ for winding at rear side of the neck of wearer. In the FIG. 4, the two shoulder straps 30 for crossing at the back side of the wearer.

It is worth to mention that the shoulder straps 30 may be detachably connected to the cups 10, 10′ or the bra body by any conventional or above described detachably fasteners or method for adjustably attaching with the bra body and/or the cups 10, 10′. Preferably, the back connecting bands 221, 221′ are detachably coupled with the outer edges 14, 14′ of the left and right cups 10, 10′ respectively.

As shown in FIGS. 2A and 2B, the side sectional views of each of the conic shaped left cup 10 and right cup 10′ are illustrated, wherein the cavities 121 and 121′ of the left and right cups 10, 10′ respectively are having a size different from each other, so that the wearer with asymmetrical breasts is able to selectively pick up the size of left cup 10 and right cup 10′ in order to individually fit the left breast and right breast of the wearer. After the wearer chose the sizes of each of the left cup 10 and right cup 10′, the wearer is able to assemble the separated left and right cups 10, 10′ to form the bra with different sizes of the two cups 10, 10′, so as to optimize the fit of the bra. Therefore, the bra of the present invention having better fit, especially for wearer with asymmetrical breasts, is able to optimize the function of supporting, covering, shaping the breasts of the wearer via the bra.

Accordingly, the sizes of the cavities 121 and 121′ can be formed and determined by any conventional method, such as filling, and standard measurement, such as size of A cup, or B cup. The size of each of the cups 10, 10′ may be determined by variety of factors, such as the volume of the cavities 121, 121′, the height from the bottom of the conic shaped cup to the apex point thereof, and/or the position of the central apex point of the cups 10, 10′.

In this case, a first filling 101 is provided for being sandwiched between the convex front cup face 11 and the concave rear cup face 12 of the left cup 10 to integrally form the left cup 10. A second filling 101′ is provided for being sandwiched between the convex front cup face 11′ and the concave rear cup face 12′ of the right cup 10′ to integrally form the right cup 10. Thereby, the sizes of the cup cavities 121, 121′ of the left and right cups are able to be determined via the fillings 101, 101′. The filling material can be fabric, foaming material, or the likes for providing the predetermined cushioning of the cups, so as to comfortably support the breasts of the wearer. It is worth mentioning that the cup size of each of the left and right cups 10, 10′ is non-adjustable such that no padding is needed to add to adjust the cup size thereof. In other words, the cup cavity 121, 121′ of each of the left and right cups 10, 10′ is pre-configured in a non-adjustable manner for well supporting the respective breast of the wearer.

Alternatively, the left and right cups 10, 10′ may be formed via one single piece material having the desired shape the thickness to form the variety of sizes of the cups 10, 10′, wherein the front cup faces 11, 11′ and the rear cup faces 12, 12′ are integrally formed at two opposite sides of the single piece material of each of the left and right cups 10, 10′. Therefore, the material of the cups 10, 10′ are preferably fabric, or any other materials having the predetermined elasticity or cushioning characteristic for providing the cushioning feature, such as foaming material.

Therefore, the wearer is able to individually select the sizes of each of the left cup 10 and the right cup 10′ of the bra of present invention without alternating the structure of the bra to compromise the supporting force or comfortableness of the bra when being worn by the wearer. It is appreciated that each of the left and right cups 10, 10′ can be formed a size between any two of the existing standard sizes, such as between size A and B cup of the existing cup size of bra.

In order to provide a symmetrical outer appearance when the bra is being worn by the wearer, the left and right cups 10, 10′ preferably have an identical outer shape of the convex front cup face 11 and 11′ while having different sizes of the cup cavities 121, 121′ of the left and right cups 10, 10′. Therefore, the front cup faces 11 and 11′ may have the same shape while the rear cup faces 12 and 12′ may have different shapes for individually fitting each of the left breast and right breast of the wearer. In other words, the size of each of the cup cavities 121, 121′ may be different from each other via adjusting the fillings or the thickness of the cups 10 and 10′.

As will be readily appreciated by one skilled in the art, one or both of the cups 10, 10′ of the bra may have a protruding portion protruded out from the bottom of the rear cup face 12 or 12′, so that the bra is able to perform the push-up function thereof or for a better fit for minimizing any seams between the breasts and the corresponding cups 10, 10′. For instance, the left cup 10 has a cavity size the same as existing cup size D, while the right cup 10′ has a cavity size the same as existing cup size C, wherein the right cup 10′ may have relatively thicker filling or material with extra protruding portion as mentioned above for fitting and lifting up the right breast of the wearer, so as to have a substantially symmetrical appearance of the breasts, as shown in FIGS. 2A and 2B.

As shown in FIG. 3, an alternative bra body 20A of the bra is illustrated, wherein the bra in the FIG. 3 has the similar structure and function as mentioned in the above preferred embodiment of the present invention. The following description will focus on the chest band 201A of the alternatively bra body 20A.
